I had a composite filling (or at least I think that's what the tooth color, non-metal fillings are called) done last week on a front tooth--number 7. After the anesthetic wore off, there was still a slight dull pain which I initially ignored. I had actually gotten work done on tooth 8 as well and though that because the dentist had "sanded" in between my teeth and irritated my gums that it was just pain from that. I had initially expected the work to be located between the two teeth, but he said he noticed decay on the front face of the teeth (which I'm not sure I believe, I know my tooth surface was not smooth because the orthodontist I had only roughly sanded away cement--though he may have predestined the tooth to decay, orthodontic work was removed about 4/5 years ago) and I believe he drilled that away and filled it too as it is not covered with the filling material. However, now, a week later, my gums look fine to my sight. And I have noticed the dulling pain has not gone away (only tooth 7 hurts), and in fact it is now extremely sensitive to touch even slight movements like smiling makes my tooth feel like there is a swelling pain, and it is also sensitive to hot and cold--hot is painful for about a minute or two, and cold is not painful for the first 30 seconds or so but then there is a sharp pain that also lingers for a minute or so. I have searched online and have seen a couple possible reasons why this may be but I would love another opinion. I am very concerned because I am away from home for the summer and so cannot get to my own dentist, but am wondering if I should go to another dentist right away or wait a few weeks. The pain has started to become disruptive in my everyday life, but if it is something normal I may be able to train myself to ignore it a while longer. I have not used any medications, oral or topical, for this toothache or anything else since getting this work done.
